Senior Operations Associate, Office of the CEO

About Coefficient Giving

Coefficient Giving (formerly Open Philanthropy) is a philanthropic funder and advisor. Since 2014, we’ve directed over $5 billion in grants as part of our mission to help others as much as we can with the resources available to us. We work with a range of donors who share our commitment to cost-effective, high-impact giving. Our current funds include Science and Global Health R&D, Navigating Transformative AI, Biosecurity & Pandemic Preparedness, Abundance & Growth, Farm Animal Welfare, and more.

In 2025, we recommended more than $1 billion to high-impact causes.

We’re proud of our track record:

• We jump-started the field of AI safety and security and have played a vital role in addressing other existential threats, such as mirror bacteria.
• Our grants to evidence-backed global health programs have saved over 100,000 lives, and our farm animal welfare grants have improved the lives of over 3 billion animals.
• We supported late-stage clinical trials for the R21 malaria vaccine, now being scaled to protect millions of kids globally.
• We were the earliest major funder of the YIMBY movement to build more housing. Our grantees have led the charge on major wins like City of Yes in New York, and SB 79 in California, which will enable hundreds of thousands of new housing units.

Our CEO, Alexander Berger, is responsible for advancing CG’s overall mission. This includes:

• Setting high-level organization priorities
• Owning key external relationships, including our work with Good Ventures (our founding partner) and other major donors
• Hiring for senior roles and supporting the rest of the leadership team
• External and internal communications about CG’s culture and impact

The Office of the CEO supports Alexander by co-owning many of his priorities and setting him up to be as effective as possible. The team also supports the rest of CG’s leadership team. Abie Rohrig works as Chief of Staff in the Office of the CEO.

This is a high-trust, high-leverage role at a very exciting time for one of the world’s largest philanthropies. The Office of the CEO works closely with CG’s senior leadership and touches nearly everything CG does, from major donor relationships to org-wide priorities, and the person in this role will see how those decisions are made up close. The right person in this role will multiply how much Alexander — and, by extension, all of CG — can get done.

We’re hiring for a Senior Operations Associate in the Office of the CEO to support Alexander Berger’s operational and administrative work. This person would report to Abie Rohrig and work primarily to extend Alexander’s capacity and focus.

Your core responsibilities would include:

• Calendar and time management: Own organizing Alexander's calendar by scheduling meetings with team members and external stakeholders, leading a calendar sync meeting with Alexander at the beginning of every week, and analyzing time allocation across key areas
• Inbox and communications management: Help triage Alexander's inbox and learn to write effectively in his voice, maintaining fast response times and building systems to track and route incoming asks
• General executive support: Handle the full range of day-to-day administrative needs, including travel planning, expenses and reimbursements, external appointments, and executive office software (Airtable, Asana, Toggl)
• Meeting and event coordination: Coordinate with internal stakeholders to gather materials and information ahead of Alexander's meetings; write meeting agenda first drafts; track and execute follow-up action items; ensure that conferences, events, and in-person visits go smoothly
• Contact and relationship management: Maintain a comprehensive database of Alexander's professional contacts and proactively surface relevant meetings and events based on current priorities and travel
• Operational improvement: Identify administrative bottlenecks and develop solutions, including AI integration; own special projects that increase efficiency and strengthen internal knowledge management
